Abstract
In the active matrix display device with a DRAM as the retaining circuit, the voltage retained in the retaining circuit is set in the brightness saturation region, which is outside the region of the voltage used in the moving picture display mode. With the voltage in this region, the difference in the brightness will not be recognized even if the voltage decreases before the refreshing operation. This prevents flickering and improves the display quality.
